Incomplete penetrance in maize genotypes segregating for the polyembryony trait

, 2020
To study the genetic control of polyembryony trait in maize germplasm a series of experiments were carried out.The genetic material came from crossings among two polyembryonic populations and 16 different genotypes,normal type maize.

Estádios de desenvolvimento embrionário e localização do embrião zigótico em sementes de citros Embryo development stage and the location of embryo zygotic in the seed of citrine

Pesquisa Agropecuária Brasileira, 1999
Objetivou-se estudar o comportamento de embriões zigóticos e nucelares aos 120, 130, 140 e 150 dias após serem efetuadas hibridações controladas entre a laranjeira 'Natal' (Citrus sinensis Osb.) e o parental masculino Poncirus trifoliata (L.) Raf.

Polyembryony in maize: histological analysis

Acta Societatis Botanicorum Poloniae, 2014
The histological analysis enabled to distinguish the main types of polyembryony in maize according to the origin of embryos connected with their localization in caryopses, differences in their structure (presence of common tissues) and type of ...

Selection of SSR markers for identifying embryonic origin in three polyembryonic mango rootstock varieties

Crop Breeding and Applied Biotechnology
Polyembryonic mango varieties, often used as rootstocks, produce two or more embryos per seed, one of which is genetically distinct from the mother plant.

Monitoring the viability of citrus rootstocks seeds stored under refrigeration Monitoramento da viabilidade de sementes porta-enxertos de citros armazenados em câmara fria

Revista Brasileira de Fruticultura, 2013
The citrus nursery tree is produced through the bud grafting process, in which rootstock is usually grown from seed germination. The objective of this research was to evaluate, in two dissimilar environmental conditions, the viability and polyembryony ...

The adaptive value of polyembryony.

, 1998
From an evolutionary standpoint, the production of offspring is the single most important aspect of an animal's life. Offspring carry an individual's genes into the next generation and it is the differential representation of genes in a population that ...
